Ladies and Gentlemen:

We have acted as counsel to Agree Limited Partnership, a Delaware limited partnership (the “Issuer”) in connection with the issuance and sale of $350,000,000 aggregate principal amount of the Issuer’s 2.000% Senior Notes due 2028 (the “2028 Notes”) and the issuance and sale of $300,000,000 aggregate principal amount of the Issuer’s 2.600% Senior Notes due 2033 (the “2033 Notes”, and together with the 2028 Notes, the “Notes”), which have been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to a registration statement on Form S-3 (File No. 333-238729), as amended by the Post-Effective Amendment No. 1 and Post-Effective Amendment No. 2, each filed with the Securities and Exchange Commission (the “Commission”) (as amended, the “Registration Statement”), which became effective upon filing with the Commission, with the Notes to be guaranteed (the “Guarantees”) by Agree Realty Corporation, a Maryland Corporation (the “Parent”), and the parties listed on Schedule I attached hereto (together with the Parent, collectively, the “Guarantors”).

In our capacity as counsel to the Issuer, we have examined originals or copies of (i) the Registration Statement, (ii) an indenture, dated as of August 17, 2020, among the Issuer, Parent, and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the Officer’s Certificate delivered by the Issuer and the Parent on May 14, 2021 (as supplemented, the “Indenture”), (iii) the underwriting agreement (the “Underwriting Agreement”), dated May 5, 2021, by and among the Issuer, the Guarantors, and Citigroup Global Markets Inc. and Wells Fargo Securities, LLC, as representatives of the several underwriters named therein, and (iv) such other corporate and other records and documents we considered appropriate. We have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity with the originals of all documents submitted to us as copies.

The law covered by the opinions expressed in this opinion letter is limited to the following Law (as applicable and as defined in paragraph F below): (i) the Delaware Revised Uniform Limited Partnership Act (the “Delaware RULPA”) and the federal Law of the United States, (ii) the Delaware Limited Liability Company Act (together with the Delaware RULPA, “Applicable Delaware Law”), (iii) the internal Law of the State of Michigan, (iv) the internal Law of the State of Florida and (v) the internal Law of the State of New York, in each case as in effect on the date of this opinion letter, and we do not express any opinion concerning any other laws. We are not admitted to practice in the State of Delaware and, with respect to the opinions set forth below, insofar as they relate to any Delaware law, we (a) have limited our review, with your permission, to standard compilations available to us of the Applicable Delaware Law, which we have assumed to be accurate and complete, and (b) have not reviewed case law.

Our opinions set forth above are subject to the effect of any applicable bankruptcy, insolvency, reorganization, moratorium or similar law relating to or affecting creditors’ rights generally (including, without limitation, fraudulent conveyance and voidable transaction laws), general principles of equity, including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether considered in a proceeding in equity or at law and limitations regarding the availability of indemnification and contribution where such indemnification or contribution may be limited by applicable law or the application of principles of public policy.

We express no opinion as to the validity, binding effect or enforceability of (i) provisions that relate to choice of law, forum selection or submission to jurisdiction (including, without limitation, any express or implied waiver of any objection to venue in any court or of any objection that a court is an inconvenient forum), (ii) waivers by the Issuer or Guarantor of any statutory or constitutional rights or remedies, (iii) terms which excuse any person or entity from liability for, or require the Issuer or Guarantor to indemnify such person or entity against, such person’s or entity’s negligence or willful misconduct, (iv) obligations to pay any prepayment premium, default interest rate, early termination fee or other form of liquidated damages, if the payment of such premium, interest rate, fee or damages may be construed as unreasonable in relation to actual damages or disproportionate to actual damages suffered as a result of such prepayment, default or termination, usury and other interest-related restrictions, or (v) provisions providing that the terms of agreement may not be waived or modified except in writing.
